Collisional quantum interference takes place in radiationless transitions and is inherently the interference between de broglie waves . sha , zhang and co - workers [ j . chem 碰撞过程中量子干涉效应是分子碰撞导致的无辐射跃迁过程中的干涉,本质上是属于德布罗意波之间的干涉。
2.
The polyvinyl alcohol ( pva ) in precursor can improve the porosity and make the aperture distribution narrower . so the gels were not easily crazing when drying . simultaneously the fluorescence intensity of the dyes increased as a result of the probabilities of radiationless transitions 在先驱液中加入少量有机聚合物聚乙烯醇1 ( pva )不仅改善了孔结构,使孔径分布窄,凝胶在干燥过程中不宜开d裂,而且使掺于其中的染料分子的迁移运动受到限制;降低了非辐射i跃迁的几率,提高了染料的荧光强度。
